I have general questions about Botox.

Hello. Lately, fine lines around my eyes and forehead have been getting deeper, so I am considering Botox treatment. Since this is my first time getting Botox, I have a few questions. I would like to know how long it usually takes for the effects of wrinkle-reducing Botox to appear after the procedure, and how long the results last. I have heard that regular injections are necessary to maintain the effects; typically, at what intervals is it most appropriate to receive re-treatments? Additionally, I would appreciate it if you could provide detailed information on whether there are any specific restrictions on daily activities, such as washing my face, applying makeup, or exercising, or if there are any side effects I should be aware of on the day of the procedure. I look forward to your reply.
